I made a PHP script which lets me use a template file, but I'm having some problems. I am unable to use other php code within the $content variable. (I can't echo the time or include something) Here is the code that I use for my index page:
<BLOCKQUOTE>code:<HR><pre>
<?php
$title = 'chrisellsworth.net | home';
$validate = 'yes';
$content = '

<div class="center">
<div style="font-size : 32px">
chrisellsworth.net 
</div>
</div>

';
include 'template.php';
?>
[/code]

and here is the template code:

<BLOCKQUOTE>code:<HR><pre>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" >
<head>
<title><?php echo $title;?></title>
<meta http-equiv="content-type" content="text/html;charset=iso-8859-1" />
<link rel="stylesheet" href="/stylesheet.css" type="text/css" />
</head>
<body>
<div id="navbar">
<a href="/">home</a>
| <a href="/computers">computers</a>
| <a href="/contact">contact</a>
| <a href="/stuff">stuff</a>
</div>
<div id="content"><?php echo $content;?>
</div>
<div class="center">
 
<?php if ( $validate == "yes" ) {
echo( '<a href="http://validator.w3.org/check/referer"><img
src="http://www.w3.org/Icons/valid-xhtml11"
alt="Valid XHTML 1.1!" /></a>
<a href="http://jigsaw.w3.org/css-validator/validator?uri=http://www.chrisellsworth.net/stylesheet.css"><img
src="http://jigsaw.w3.org/css-validator/images/vcss" 
alt="Valid CSS!" /></a>' );
} else {
echo( '<a href="http://jigsaw.w3.org/css-validator/validator?uri=http://www.chrisellsworth.net/stylesheet.css"><img
src="http://jigsaw.w3.org/css-validator/images/vcss" 
alt="Valid CSS!" /></a>' );
}
?>
</div>
</body>
</html>
[/code]

Nevermind my previous post. I misunderstood. I think that your problem is the '. It's a literal and will not process any php variables contained within it. Use a double quote instead. I would just echo those lines and make sure you escape the " with a \. If you need to reuse the code repeatedly, put it in a function and call it when you need to. Or maybe I'm misunderstanding your problem

Yup... you understood correctly. The way I wrote the script is really weird, I think I'm gonna go back to class.FastTemplate. I'll wait until I know some more code before I make my own template engine.

In this context, you should use "require 'template.php';" rather than "include 'template.php';". It'll execute faster. Use include only inside of conditional tests, where the code may or may not be included, and require everywhere else.

Thanks for the tip.

PHP4 supports Perl style here documents, which may help you out when doing basic templating stuff (although the syntax is a little different than Perl's)

<?php
$title = 'chrisellsworth.net | home';
$validate = 'yes';
$content = <<< HTML
My title is $title 
This is some more content.
Notice I can include variables like $validate 
Right with my HTML, and I don't have to escape anything either.
<a href="home">$title</a> 
HTML;

Now, when you print $content in your template, PHP will parse in the values of those other variables.

The 'HTML' which starts and ends the here document can be anything you want, it just has to be the same at the start and end. Also note that you must make sure there are no characters (that includes whitespace) after the initial HTML or the ending HTML; -- if there are, PHP will throw an error.

Hope that helps!

Cool... I'll keep that in mind.
